Thanks, the close code solved it

Hi all, This might be silly question but I couldn't manage to do it :( I just need to save the residual displacement to a file. I know that the recorder gives all the displacements and the last one will be the residual, however, I need the output file to contain only the residual displacement. I use...

Thank you very much. I just plotted the top displacement vs the base moment for each analysis and since the difference between including/excluding P-Delta effect (with current input) is small, the two graphs seems to be identical. And as I was expecting a big difference (50-100mm like a previous stu...

Thanks for reply. The displacements are not 0, but the same results for both cases. Here is the code which is a cantilever column with axial load. I used LA01 earthquake record, just use any. Thanks for help. # SET UP ----------------------------------------------------------------- wipe; # clear me...

Hi there, thanks for replying. Yes, I am using the loasdConst command. Here is the code for applying the axial load P : geomTransf PDelta 1; element nonlinearBeamColumn 1 1 2 4 100 1; pattern Plain 1 Linear { load 2 0 [expr -0.05*$Weight] 0 }; set Tol 1.0e-12; test NormDispIncr $Tol 10; constraints ...

Hi all, I tried a nonlinear time history analysis on a cantilever column to see P-Delta effect on the results. To include P-Delta I used PDelta geometric transformation, to ignore it I just used the Linear geometric transformation. The problem was that the two results were identical :\ I tired to in...

Hi there,
there is an example about moment-curvature, just take a look at it

Hi all, I am performing pushover analysis and when unloading I don't know how to set the displacement to 0 force position (the origin) so that I can push again from the same starting point. I am just checking the concrete material (Concrete04) and I want to get the stress-stain diagram with loading-...

Dear admin :) Kindly know that there are some errors in examples 2b and 2c in pushover part, they exists in this forum, following are the links: http://opensees.berkeley.edu/wiki/index.php/OpenSees_Example_2b._Nonlinear_Cantilever_Column:_Uniaxial_Inelastic_Section http://opensees.berkeley.edu/wiki/...

What did u mean by "this"? its a link to UniaixialMaterial Command

Thanks Alperozturk,
but "Compressive concrete parameters should be input as negative values (if input as positive, they will be converted to negative internally)."

Which Concrete material did u use? if you used Concrete02, try using Concrete01 and see what will happen

Hello guys, I had a convergence issue when I used Concrete02 material in a gravity load analysis. However, when I changed it to Concrete01 (no tension strength for concrete) it worked just fine. Any idea why this happened? Thanks Here is the code: # MATERIAL parameters # confinded concrete set fpc [...

Ok, and thanks
